2. Messaging Apps
Messaging apps with call capabilities, like WhatsApp, Viber, and Facebook Messenger can be used to make calls without a sim card.
How does this work? Messaging apps use your internet connection (Wi-Fi or mobile data) to make voice or video calls, so you don’t need a SIM card. For example, if you have WhatsApp installed on your phone or computer, you can use it to call friends or family anywhere in the world as long as you are connected to the internet.
Similarly, Viber and Facebook Messenger offer the same functionality, enabling you to place calls to anyone who has the app, regardless of their location.

3. Dedicated Calling Apps
Dedicated calling apps allow you to make phone calls without a sim card by using an internet connection rather than relying on a SIM card or traditional phone service. These apps often provide users with a unique phone number or use existing accounts for call functionality.
How does this work? Dedicated calling apps use VoIP technology to connect your call over the internet. All you need is a device (smartphone, tablet, or computer) and a stable Wi-Fi or mobile data connection. These apps let you make and receive calls as if you were using a regular phone line, but without the need for a physical SIM card.
Practical Examples:
- Google Voice: This app allows you to make calls, send texts, and even check voicemails. Users get a free phone number that can be used to make calls over Wi-Fi or data, which is perfect for staying connected while traveling or managing different numbers for work and personal use.
- Line: Popular in many Asian countries, Line offers free voice and video calls over the internet. Users can call other Line users or pay a small fee to call landlines and non-Line mobile numbers.
- WeChat: This multifunctional app is widely used in China and globally for messaging, but it also allows for voice and video calls to other WeChat users without the need for a SIM card.
These dedicated calling apps are great options for maintaining communication without being tied to a physical SIM or local carrier network.
4. SmartPhone Assistants
Smartphone assistants, like Amazon Alexa, Google Assistant, and Apple’s Siri, can make calls using an internet connection, so you don’t need a SIM card to use this feature. These assistants use VoIP or integrate with apps that support internet-based calling.
How does this work? Smartphone assistants are voice-activated programs that can perform various tasks, including making calls. If your device is connected to Wi-Fi, you can ask the assistant to place a call, and it will use internet calling services to connect. For example, some assistants can make calls through apps like Skype, WhatsApp, or their own calling features.
Practical Examples:
- Amazon Alexa: With an Echo device or the Alexa app on your smartphone, you can say, “Alexa, call [contact name],” and it will place a call using your Wi-Fi connection. This works for calling other Alexa users or even regular phone numbers if you’ve set up that service.
- Google Assistant: On a Google-enabled device, you can say, “Hey Google, call [contact name],” and it will place the call over Wi-Fi using Google Duo or any compatible app linked to your account. This makes it easy to call friends and family without needing a SIM card.
- Apple’s Siri: Siri can make calls over Wi-Fi if you have the relevant settings enabled. For example, you can say, “Hey Siri, call [contact name] on FaceTime,” and the call will go through using your internet connection.
These assistants make calling without a SIM card simple and hands-free, adding convenience for home, work, or travel use.

5. Satellite phone services
Satellite phone services allow you to make calls without using a SIM card or relying on traditional cell towers. Instead, these phones connect directly to satellites orbiting the Earth to transmit voice data, making them ideal for remote areas where cellular coverage is unavailable.
How does this work? Satellite phones use built-in antennas to connect to satellites. When you place a call, the phone sends signals to a satellite, which then relays the call to a ground station. From there, the call is routed to its destination, such as a landline or mobile phone. This process works independently of cellular networks, so you don’t need a SIM card to make calls.
Practical Examples:
- Iridium Satellite Phones: Iridium phones provide global coverage through their network of low-Earth orbit satellites. With an Iridium phone, you can make and receive calls anywhere in the world, whether you’re in the middle of the ocean or deep in the mountains.
- Inmarsat Devices: Inmarsat satellite phones are popular among travelers and remote workers who need reliable communication in regions where cellular service is not available. Users simply power on the phone, connect to the satellite network, and dial a number to make calls.
- Globalstar Phones: These devices are often used for emergency services, expeditions, or remote fieldwork. With a Globalstar phone, users don’t need a SIM card; they just need to connect to the network and make calls using the device’s built-in functionality.
Satellite phone services are essential for those who travel to remote areas or work in industries like maritime, aviation, and disaster response where reliable communication is critical.
6. Web RTC
Web Real-Time Communication (WebRTC) is a technology that allows you to make voice and video calls directly from a web browser without needing a SIM card or additional software. It uses your internet connection to establish a secure connection between two or more users for real-time communication.
How does this work? WebRTC is built into modern web browsers like Google Chrome, Mozilla Firefox, and Microsoft Edge. When you use a WebRTC-supported website or web application, the browser connects to other users over the internet. This technology handles the audio and video transmission securely, making it possible to call someone with just a few clicks.
Practical Examples:
- Google Meet: You can use Google Meet directly from your browser to make voice and video calls with colleagues or friends. No SIM card is needed—just an internet connection and a web browser.
- Web-based Chat Platforms: Platforms like Jitsi Meet and appear. in (now known as Whereby) offer free, browser-based video and voice calls. Users can create a call link, share it, and connect with others without needing a phone number or SIM card.
- Slack Calls: Many teams use Slack for communication, and its web version supports voice and video calls through WebRTC. Users can start a call within a Slack channel or a direct message, all from the web browser.
WebRTC makes it easy to stay connected and communicate effectively without needing a physical SIM card or traditional phone service, simply by using the power of your browser and an internet connection.

7. WiFi Calling
Wi-Fi calling also allows you to make calls without a sim card. All you need is an internet connection instead of a traditional mobile network. This is helpful if you have poor or no cellular signal but a strong Wi-Fi connection.
Here’s how it works:
- Wi-Fi Connection: Your phone connects to the internet through Wi-Fi (like at home, in a cafe, or at work).
- Call Through Wi-Fi: Instead of using the cellular network, the phone uses the internet (Wi-Fi) to route the call. The call works just like any regular phone call.
- No SIM Card Needed: If your phone supports Wi-Fi calling, you can still make and receive calls even without a SIM card, as long as you’re connected to Wi-Fi. This is especially useful for people who don’t want or can’t use a SIM card but still want to make calls.
Practical Example:
- Imagine you’re traveling abroad and don’t want to use international roaming services, or you’re in an area with no mobile signal but have access to Wi-Fi. With Wi-Fi calling, you can still call your friends and family as if you were using a regular network.
You’d need to ensure your phone and carrier support Wi-Fi calling and enable it in your phone settings. Some apps like WhatsApp, Skype, or Google Voice also allow you to make calls using Wi-Fi, which works similarly.
